Abstract

An optical detection device includes: a light source unit that emits source light; a curve-shaped light guide, that includes a light incident surface, to which the source light is incident, located in an end portion of the light guide and a convex surface from which the source light incident from the light incident surface is output; an irradiation direction setting unit that receives the source light output from the convex surface of the light guide and sets an irradiation direction of irradiation light to a direction of a normal line of the convex surface; a slight receiving unit that receives reflection light acquired by reflecting the irradiation light on an object; and a detection unit that detects at least a direction in which the object is located based on a result of the light reception in the light receiving unit.
